Reliability demonstration testing for software products is performed for the purpose of examining whether the specified reliability is realized in the software after the development process is completed. This study proposes a model of reliability demonstration testing for continuous-type software such as that for controlling production lines and operating systems of computers. Testing time and acceptance number of software failures are designed based on variation distance. This model has less...

Reliability demonstration testing for softwareproducts is performed for the purpose of examining whetherthe specified reliability is realized in the software after thedevelopment process is completed. This study proposes a modelof reliability demonstration testing for discrete-type softwaresuch as software for numerical calculations. The number ofinput data sets for test and acceptance number of input datasets causing software failures in the test are designed basedon variation distance. This...

This paper presents an improvement of a standard algorithm for detecting dead-lock potentials in multi-threaded programs, in that it reduces the number of false positives. The standard algorithm works as follows. The multi-threaded program under observation is executed, while lock and unlock events are observed. A graph of locks is built, with edges between locks symbolizing locking orders. Any cycle in the graph signifies a potential for a deadlock. The typical standard example is the group of...
